Finders Keepers, by Stephen King

A sequel to Mr. Mercedes.

This, like almost everything I've ever read by Mr. King, did not disappoint.

It's the story of a family that was affected by the tragedy central to the plot of Mr. Mercedes.  In particular, it's about a young man who literally finds buried treasure, and uses it to help his family. When the burier of the treasure is released from prison prematurely, the plot picks up speed.
